Water Resistant is a common mark stamped on the back of wrist watches to indicate how well a watch is sealed against the ingress of water. It is usually accompanied by an indication of the static test pressure that a sample of newly manufactured watches were exposed to in a leakage test.
Waterproof (or water-resistant) describes objects unaffected by water or resisting water passage, or which are covered with a material that resists or does not allow water passage. In horology, the waterproofness of a watch is defined by its resistance under pressure.
Water resistance is measured by the amount of water, in mm, which can be suspended above the fabric before water seeps through. [ citation needed ] Breathability or moisture vapor transmission rate is measured by the rate at which water vapor passes through, in grams of water vapour per square meter of fabric per 24-hour period (g/m 2 /d), [ 2 ...
The IP code on a mechanical or electrical enclosure indicating its ability to resist the ingress of water; Wet strength, a measure of the strength of paper when wet; Waterproofing, making objects or structures resist the ingress of water under specified conditions; Fluid resistance, drag in water; Lotus effect (water-resistance in plant leaves)
Waterproofing conducted on the exterior of a freeway tunnel. Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions.
A diving watch, also commonly referred to as a diver's or dive watch, is a watch designed for underwater diving that features, as a minimum, a water resistance greater than 1.1 MPa (11 atm), the equivalent of 100 m (330 ft). The typical diver's watch will have a water resistance of around 200 to 300 m (660 to 980 ft), though modern technology ...
Harvard University removed human skin from the binding of "Des Destinées de L'âme" in Houghton Library on Wednesday after a review found ethical concerns with the book's origin and history.
Crystal structure of β-glucosidase from Thermotoga neapolitana (PDB: 5IDI).Thermostable protein, active at 80°C and with unfolding temperature of 101°C. [1]In materials science and molecular biology, thermostability is the ability of a substance to resist irreversible change in its chemical or physical structure, often by resisting decomposition or polymerization, at a high relative ...
